To alt/whom it may concern: v

Be it known that I, LEOPOLD DE MnU'r'rnR, a subject kof Belgium,V residing in the city and county of `San Francisco and State of California,V have invented a new and useful Improvement ina Gas-Plate, of which the following is a specification.

My inventionrelates to improvements in gas plates wherein a plurality of indepen'd` ently regulatedwapertured conduits operate-v in conjunction with baflies te 4deliver kand -evenl'y distribute a gaseous fuel for Combusf beneath a heating surface;

supply of fuel and-regulating the combustion"thereofwhereby a `heating surface may be vheated evenly or to varying degrees at differentportions thereof as desired.

'gas plate, a portion of the heating surface being broken away to disclose the arrangement of conduitsand bafflesthereunder;

Fig. 2 is a broken sideelevation ofFig. 1; l

Fig. 3 isa Crosssectional view taken along the line 3-3 of Fig. 2 in the direction indicated.

` Referring to the drawings the numeral 41 is usedto designate a heatingsurface supported adjacent' the corners thereof upon machine bolts adj ustably mounted in fittings 3 provided at the upper endsof supporting pipes 4 vconnected at the upper 'ends thereof `bytransverse-braces 6-rnou`nted within the fittings 3. Fuel conduits 7 provided with'a plurality of apertures 8 extend longitudi nally beneath the heating surfacel and are 'secured at the ends thereof in the fittings 3 mounted upon the supporting pipes 4L, a centrallydisposed conduit 7 being'provided and secured within fittings 9 provided in the transverse braces 6. ne pairof supporting 'pipes t is connected at the lower end thereof with supply conduits y11 kfor delivering yfuel therefromv to the fuel conduits 7 thecentr'al fuel conduit-7 being similarly connected tO-V receive fuel from asimilar supply conduit 11.

*A ma-insupply conduit 12 is connected to the supply conduits 11 by fittings 14 for delivering'fgaseous fuel thereto from a source `of .supply-'not shown',` a valve 16 being provided in saidmain supply conduit for regulating vthe amount of fuel supplied therefrom to the supply conduits 11.

are pro-vided in the supply conduits 11 for independently regulating the amount of fuel supplied to the fuel 'conduits 7 Transverse baffle supporting bars 18 rest u upon the fuel conduits 7 `for supporting a Third, -to provide means for adjusting the plurality 0f `baflie bars 19 arranged longitudinally in pairs in spaced relation above the fuel conduits 7 for 'distributing and causing a circulation of gaseous fuel for combustion thereabout. j

Vertically disposed side plates 21 and end plates 22 having inwardly turned lugs 24 adjacent the ends at the top and bottom edge thereof are mounted adjacent the heating *surfacey 1, said lugs 24 being provided with apertures 26 registering in corresponding upper and 4lower lugs and adapted to engage downwardly vextending rods 27 secured to the heating surface 1 on thelow'er side thereof for slidably mountingsa'id side plates 21 andend plates 22 thereon. The rods 27 are threaded at the lowerend thereof to receive afnut 28 for adjustablyretaining said side and'end plates inthe desired vertical'relation with theheating surface 1. Apertures 29 Iareprovided near the endsfof the side plates 21 and the" end plateslf22 to provide means for admitting air above thebafiles 19. Damper plates V31 are slidably'mountedl adjacent the apertures`29' for adjusting'the amount of air to be admitted therethrough, said damper` plates 31 `being retained in en -i gagement with the vside'plates 21 and'end plates 22 by springs 32 secured thereto.

The slidably` mounted side plates ,21and Adjusting valvesu17 i end plates 22 provide means of admitting air between the upper edge thereof and the heating surface 1, in variable amounts at' different sides and ends for regulating the combustion of gas thereunder tomeet varying requirements, the dampers 31 and apertures V29 forming additional regulating means adapted to meet varying conditions.` In

practice the gas delivered through the aperturefuel conduits 7 is deflected about the baffle bars 19 and circulated beneath the heating surface 1, ail` being admitted above said baffle bars 19 to cause a complete combustion thereof in direct contact with the heating surface. The independent adjusting valves 17 provided in the supply conduits provide means for regulating the supply of fuel delivered to the fuel conduits to obtain evenness of heat at all parts of the heating surfacev 1, or to cause an inequality of heating affording a hotter surface at one side than at the other. The bolts 2 are provided for adjustingPV the level of the heating surface. The transverse braces 6 are made blind t0 prevent the passage of gas therethrough from oney fuel conduit to another,

' the supporting-.pipes 4 also being made blind to revent escape o f gas therethrough.

aving thus described my Vinvention what I claim as new and desire to secure by Letters Patent is: y Y
